  • the housing can advantageously be constructed of a structural material that is light, attractive, and/or inexpensive (but possibly not fully resistant to electromagnetic radiation from the laser), but which incorporates a protective material in the design that renders the housing safe against laser radiation.
  • the protective material can be more resistant to the electromagnetic energy than the housing and thus render the housing safe against laser radiation.
  • One advantage of the composite construction is a smaller amount of laser-safe protective material can be used, with the remainder of the cheaper or lighter structural material used to provide structure or support for the rest of the CNC machine.

  • substantially can refer to a housing being greater than 50% plastic in terms of interior surface area, exterior surface area, total surface area, mass density, cross sectional dimension, or the like. Because the top surface and lid of the case have different material requirements, such as a desire to be able to see through the lid, they are typically made of a different material than the rest of the case (e.g. glass) and so, while it may also be fabricated using the techniques shown here, are not included in the consideration of whether the case is substantially plastic.
  • a housing constructed substantially of plastic incorporating a protective material in other implementations specific or smaller portions of the housing can incorporate the protective material, or a different type of protective material.

Also, in implementations where the housing does not need protective material everywhere, then protective material can be added to the portions of the housing that can benefit from it. These portions can be, for example, plastic, wood, or the like. In such implementations, the housing is not substantially made of plastic. Also, in implementations where the need for protective material depends on the use or application of the CNC machine, the protective material may be added or removed to meet situational safety requirements.
